The faceted surface is what sold me—those little ridges seem to give my pup something to really grip while she gnaws. Natural latex has held up way better than the plush toys she destroys in a day.

My dog is a heavy chewer and usually destroys toys in a day, but this latex one has survived a solid week so far. The faceted shape makes it roll in weird directions, which keeps him chasing it around the kitchen.

The faceted surface is what sold me, my shepherd loves how it rolls unpredictably across the kitchen floor. Natural latex means it's held up through weeks of chewing without a single tear.
